Although a geologic map displays the geographic distribution of the different geologic units and rock types for numerous purposes, this data set is compiled primarily for the World Energy Project as part of a required strategic base for assessing the petroleum potential of this region. For this purpose, the map basically provides an outline of the general geographic distribution of both known or hypothetical petroleum-potential formations and units, i.e., sedimentary rocks and basins, and areas containing igneous and metamorphic rocks which have virtually little or no potential. The map is also compiled, in part, to provide a basis for outlining the geographic and petroleum provinces of coverage PROV1. This basic geologic data set, combined with others, such as tectonic and burial histories, distribution of known oil and gas fields, distribution and quality of reservoir rocks, organic geochemistry, etc., will ultimately define the basis for the assessment of undiscovered oil and gas in the Former Soviet Union.

Overall accuracy is based on accuracy of general geology coverage.
Since all the attributes are of character type, only
correctness of polygon labelling can be provided (see below).
Attributes and contacts are verified via visual editing and review.
A minimum of two reviewers examine and compare digital versions
versus orignal material.
A comparison between color plot and original paper map was
carried out by visual comparison. Color plots in 1:7,500,000
scale were superimposed on each of corresponding original
map sheets. All errors detected in attributes were corrected.
1. Original geological maps are of 750 meter maximum accuracy
(0.1 mm on paper map of 1:7,500,000 scale)
2. Scanned images are of 200 dot/inch resolution
(0.1 mm on paper). That is why fuzzy tolerance for CLEAN
programm in ARC/INFO is set to 1500 m (two pixels).
3. Several steps are taken to vectorize scanned images.
The projection and coordinate system for the original map
are not given. Therefore it is necessary to georeference
the map to real world coordinates. This is done as follows:
3.1. The latitude/longitude graticule with cell size 4 * 6 degree
is projected to Equidistant Conic projection and then used to
create ARC/INFO point coverage. That point coverage is used
to create "to - from" links by ARC/INFO CONTROLPOINTS program.
3.2 A gray-scale scanned image of the original paper map is
transformed to Equidistant Conic projection by ARC/INFO GRIDWARP
program (polynomial of the second order) using the "to - from"
links created by CONTROLPOINTS program.
3.3 The scanned image from the second step is vectorized by
the method of extraction of linear features described by F.Persits,
1997, (USGS open-file report OF-97-713), and then corrected by
hands-on digitization.
3.4 A series of piecewise "rubbersheet" transformations are
applied to the final ARC/INFO coverage. The ARC/INFO coverages
that are used for transformation were ESRI's ArcWorld 1:3 million GIS
cartographic layers.
Overall position error is estimated with a randomly selected set
of locations on the ESRI coverages and comparing the same locations on
the final geology coverage (geo1). RMS error is 4.8 km (0.64 mm
of the original paper map) with maximum error about 12 km (1.6 mm
on original paper map).
